342 Seeb. Spec. discharged a number of times corresponding to the duration of the successions of impulses received. Obviously the special applicanes used in carrying out my invention may be varied in many ways without departing from the spirit of the same. It is to be observed that it is the function of the cylinder, A, with its brushes and connections, to render the electrical impulses caning from the plates P and P¹ suitable for charging the condenser (assuming them to be unsuitable for this purpose in the form in which they are received) by rectifying them when they are originally alternating in direction, or by selecting such parts of them as are suitable when all are not, and any other device performing this function will obviously answer the purpose. It is also evident that a device, such as I have already referred to, which offers a more ready passage to impulses of one sign or permits only impulses of the same sign to pass, may also be used to perform this selective function in many cases when alternating impulses are received. When the impulses are long and all of the same dire tion, . and even when they are alternating but sufficiently long in duration, and sustained in electromotive force, the brushes band b' may be adjusted so as to bear on the parts B B¹ of the cylinder A, or the cylinder and its brushes may be omitted and the terminals of the condenser connected directly to the plates P and P. A It will be seen that, by the use of my invention, results hitherto unattainable in utilizing disturbances or effects transmitted through natural media, may be readily -13
